When many people choose to switch to electric cars, there are significant demands placed on the infrastructure to easily charge their vehicles wherever they are. One company contributing to this transition is CTEK. Their charging stations and Nanogrid systems help property owners, individuals, and others to provide a charging solution that works without overloading the power grid. To reduce excess work for the support department, a user interface was developed, allowing installers to configure and build a system themselves. The developed user interface focused on simplicity, scalability, and speed. Through an iterative, user-centered design process, which included a preliminary study, prototype development, implementation, and user testing, an interface with an interactive tree diagram was created. The preliminary study consisted of a literature review where theories on usability, UX design, interaction design, user-centered design, iterative design processes, impact mapping, and visualization methods were analyzed. A Lo-Fi prototype was developed and used in several user tests to ensure the new interface met the established expectations. Based on the user tests, an interface was developed. The implementation is a web application with an interactive tree diagram that allows users to add, edit, and remove charging stations and fuses in the configuration. The final product shows promising results, but parts of the interface require further development to handle error management and reduce repetitive tasks.
